Kernrechtsfrage
Whether the pension could be revised and revoked under the transitional provisions for unclear complaints.
Extrahierter Entscheid
The case had to be sent back because the medical basis was not sufficiently current and specialized to support revocation.
Extrahierte Begründung
Although the original pension had been granted for an unclear complaint picture and the transitional revision rules in principle applied, the revision required a thorough, up-to-date, specialist assessment. The existing somatic investigation was too limited and outdated to justify abolishing the pension.
